Observation of 2D Cherenkov Radiation
Physical Review X, 2023 For over 80 years of research, the conventional description of free-electron radiation phenomena, such as Cherenkov radiation, has remained unchanged: classical three-dimensional electromagnetic waves.

Cherenkov Gravitational Radiation during the Radiation Era [PDF]
Universe, 2021 Cherenkov radiation may occur whenever the source is moving faster than the waves it generates. In a radiation dominated universe, with equation-of-state w=1/3, we have recently shown that the Bardeen scalar-metric perturbations contribute to the ...

Gamma-ray Cherenkov-transition radiation [PDF]
EPL (Europhysics Letters), 2013 The production of gamma-ray Cherenkov-transition radiation (GCTR) by charged particles in the photon energy region 0.8 - 2 MeV is studied theoretically using the results of the recent discovery that in the above mentioned region the dielectric constant or the refraction index of some materials is greater than 1 due to Delbruck scattering on Coulomb ...

Accelerated-Cherenkov radiation and signatures of radiation reaction [PDF]
New Journal of Physics, 2019 In this manuscript we examine an accelerated charged particle moving through an optical medium, and explore the emission of accelerated-Cherenkov radiation.

Cherenkov radiation in a strong magnetic field
Physics Letters B, 2020 According to quantum electrodynamics, in a strong magnetic field that is constant and spatially uniform, the vacuum becomes polarized with a refractive index greater than unity.

Vacuum Cherenkov radiation at finite temperature
Physics Letters B, 2022 In this paper we examine the thermal effects of the vacuum Cherenkov radiation in a Lorentz- and CPT-violating electrodynamics. We compute the thermal contribution to the Cherenkov radiation rate within the Thermofield Dynamics approach.

TACHYONS AND GRAVITATIONAL CHERENKOV RADIATION [PDF]
Modern Physics Letters A, 2011 We calculate the rate at which a free tachyon (faster than light particle) would emit gravitational radiation. It is very small.
